The LS-5 is a programmable sensor that is used to measure liquid level in metal or plastic containers. The sensor shows the measured liquid level on an integrated display while the programmable analog and switching outputs communicate critical process information to a control system.
The LS-5 sensor generates a low power electromagnetic pulse that is conducted down the probe. When this pulse contacts a liquid, a portion of that pulse is reflected back to the sensor. The time it takes for this pulse to be transmitted down the probe and reflected back is captured and then converted into a linear distance. This technology is also known as guided wave radar.
